General Information
Koldwave 5WK Series Air Conditioners and
Heat Pumps are portable, water-cooled units
designed for applications where outside air
is not available and spot cooling is required.
The Koldwave air-conditioner cools an
entire area by discharging air through its
supply grille. Only power and condenser
water supply, water discharge, and
condensate drain piping are required for
installation.
The water-cooled condenser requires only
that amount of water needed to achieve the
desired high and low refrigeration system
pressures. The minimum condenser water
pressure for 85°F entering water temperature
can be found in the Specification and
Electrical Data section in this manual. A
refrigeration system head pressure actuated
water regulating valve regulates condenser
water.
Each unit is completely self-contained with
the entire refrigeration system, electrical
components, condenser and water valve
housed in one cabinet. All Koldwave units,
except the 5WK07, are provided with
heavy-duty casters. Two swivel-locking
casters prevent sliding; two stationary
casters provide handling ease for relocation.
The Koldwave 5WK07 is supplied with pads
on the bottom of the unit.
To attain the proper control of the water
flow rate entering the automatic water valve,
refer to the Specification and Electrical Data
Section to find the minimum water pressure
required for the condenser water supply.
The condenser water temperature leaving
the unit should not exceed 100°F. Ignoring
this compliance will void the warranty on
the refrigeration system. On heat pump
models it is not recommended to operate the
unit in the heating cycle when the water
temperature is below 50°F. Doing so could
reduce the specified heating capacity and
may cause the freeze control to cycle the
compressor off, resulting in a loss of
heating.
Model 5WK26
With the heat pump option the user can
manually select between the HEAT and
COOL functions using the touch pad control
panel or using the optional remote control.
